To change python version
sudo update-alternatives --config python3
If presented with error ModuleNotFoundError: No module named 'apt_pkg' then likely your current version of Python3's apt got messed up when changing default Python3. You likely have an apt_pkg but it's for a different version of your Python3. Some solutions may suggest a solution involving a symlink, but that can cause even more problems down the road.
Instead, you're going to look at which versions of Python3 you have to change your default version to one that matches . Then change directories to the dist-packages:
cd /usr/lib/python3/dist-packages
Run this command to locate .so files in the directory. They will look like:
sudo ln -s apt_pkg.cpython-{your-version-number}-x86_64-linux-gnu.so apt_pkg.so
| Now, change your default version using #^edec4c | this Private or Broken Links The page you're looking for is either not available or private! command, found previously in the documentation. Make sure the number you choose corresponds with one of the existing .so files. Now, try running that ppa command again and it should work. |
